Explainer: Google, Facebook battle Australia over proposed revenue-sharing law

Alphabet Inc’s Google has vowed to withdraw its main search engine from Australia, while Facebook Inc says it will block news sharing if the government proceeds with a law to make them pay domestic media outlets for content they feature.

The dispute is being closely watched worldwide since it would be the biggest challenge yet to how the U.S. tech companies that dominate social media and search engines use news on their websites.
